#33226 [WFx]: php 5.0.4 no longer detects endianness when cross-compiling
ID: 33226 User updated by: jbparsons at ucdavis dot edu Reported By: jbparsons at ucdavis dot edu Status: Wont fix Bug Type: Compile Failure Operating System: linux PHP Version: 5.0.4 New Comment: what's wrong with AC_C_BIGENDIAN? Previous Comments: [2005-06-03 08:02:31] [EMAIL PROTECTED] Yes, life is hard sometimes. If you can provide a reliable way to detect endianness when cross-compiling, feel free to send a patch. [2005-06-03 02:32:18] jbparsons at ucdavis dot edu Description: php 5.0.3 and earlier used AC_C_BIGENDIAN during configuration to detect the endianness of the target system. This autoconf macro is capable of detecting the endianness of many systems even when cross-compiling. php 5.0.4 now uses AC_TRY_RUN instead, which means that it is no longer able to detect the endianness of a target, and it must instead be configured manually. This makes it harder to configure php correctly when building for embedded systems, such as the Linksys nslu2, where this problem was noticed. -- Edit this bug report at http://bugs.php.net/?id=33226&edit=1
#33227 [NEW]: zend_strtod() broken on big-endian arm
From: jbparsons at ucdavis dot edu Operating system: "unslung" - www.nslu2-linux.org PHP version: 5.0.4 PHP Bug Type: Reproducible crash Bug description: zend_strtod() broken on big-endian arm Description: On big-endian arm systems, php sometimes crashes (infinite loop) inside zend_strtod(). The problem seems to be the code at line 261 of zend_strtod.c, which apparently assumes that every arm system has little-endian integers: #if defined(IEEE_LITTLE_ENDIAN) + defined(VAX) + defined(__arm__) #define Storeinc(a,b,c) (((unsigned short *)a)[1] = (unsigned short)b, \ ((unsigned short *)a)[0] = (unsigned short)c, a++) #else #define Storeinc(a,b,c) (((unsigned short *)a)[0] = (unsigned short)b, \ ((unsigned short *)a)[1] = (unsigned short)c, a++) #endif Reproduce code: --- Expected result: startend Actual result: -- (gdb) run Starting program: /share/hdd/data/home/jp30/t/php foo.php start [...minutes pass, then Ctrl-C is pressed...] Program received signal SIGINT, Interrupt. 0x00146528 in zend_strtod () (gdb) bt #0 0x00146528 in zend_strtod () Cannot access memory at address 0x4 -- Edit bug report at http://bugs.php.net/?id=33227&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33227&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33227&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33227&r=trysnapshot51 Fixed in CVS:http://bugs.php.net/fix.php?id=33227&r=fixedcvs Fixed in release:http://bugs.php.net/fix.php?id=33227&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33227&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33227&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33227&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33227&r=support Expected behavior: http://bugs.php.net/fix.php?id=33227&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33227&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33227&r=submittedtwice register_globals:http://bugs.php.net/fix.php?id=33227&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33227&r=php3 Daylight Savings:http://bugs.php.net/fix.php?id=33227&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33227&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33227&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33227&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33227&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33227&r=mysqlcfg
